1 Claim.

My invention relates to improvements in fountain pens, and the generalobject of my invention is to provide a greater ink storage capacity forthe fountain pen.

Another object of my invention is to provide means for filling the inkcontainer of the fountain pen.

A further object of my invention resides in the novel form andconstruction of the pen body. whereby only the writing point of the penis exposed to the outer air when the pen is in use.

Still another object of my invention resides in the novel ink wickconstruction and operation, whereby the ink is kept in uniform ow asclose to the point of the pen as is practicable.

My invention has other minor objects, all of which willbe clearlyunderstood from a perusal of the following detailed description, takenin connection with the accompanying drawing, and in the drawing:

Figure 1 is a longitudinal sectional view of my f fountain pen byitself, the view beingdn broken formation to facilitate illustration,the pen being ready for use on removal of the protecting closure.

Figure 2 is a cross-sectional view on an enlarged scale of Figure 1, theView being had on the line 2 2 of Figure 1.

Figure 3 is a view of one side of a pen, per se.

Figure 4 is an enlarged side View of the pen nib,

. opposite to that shown in Figure 3.

Figure 5 is an enlarged end View of the pen nib, and

Figure 6 is an enlarged detail cross-sectional View of the pen nib, hadon the line 6 6, Figure 3.

Referring now in detail to the drawing, and wherein like parts aredesignated by like numerals, the barrel I of my fountain pen ispreferably made of transparent material, or partly of such material, soas to enable the user to see the amount of ink in the container. One endof the barrel is threadedly engaged, as shown in Figure 1, to a thimble2, carrying a check Valve 3, of ball or any preferred type, and normallyseated over the valve duct 4. A cap 5 is threadedly secured to the outerend of the thimble and fastened to the cap is a piece of rubber 6 or thelike of resilient nature, which serves to hold the valve 3 rmly in placewhen the cap 5 is screwed down tightly.

Fastened in the opposite end of the barrel I is a plug 'I which istapered as shown and over this tapered portion is secureda transparentnipple 8, the extremity thereof carrying a metallic member 9 with anopening through which projects the (Cl. 1Z0-42) pen nib I0 of anypreferred type of pen. The upper portion of the nib III is seated in a.recess in the plug as show'n in Figures i and 2 and par tially embracesa, tongue I3, carried by the plug 1. 'I'hus the space between thethimble 2 and the inner end of the plug 1 provides an lnk container R ofrelatively large capacity.

Attention is here directed to the fact that the nib of the pen is on aplane directly in line with the opening A in the member 9, hence thewriting point of the pen is centralized in the pen, similar to a leadpencil and the pen is not held off-center as in ordinary fountain pensand pen holders. 'I'his makes for easier writing. In the drawing, Figure1, the ball point of the pen is drawn larger than actual size tofacilitate clearness, but in reality the ball point is small enough topass through the opening A when replacing. or y taking off theinipple 8to fill pen or any other purpose. The1J opening A is large enough alsoto permit some play of the pen nib. Also in addition to the customaryslit II' there is a slit II" at right angles thereto.

Spaced from the nipple 8 is a transparent closure nipple I4 threadedlyengaged to the barrel I, as clearly shown in Figure 1. Apertures Bpermit air to enter the nipple 8 to prevent clogging the ink duct I 5.'I'hus the nipples I4 and 8 provide a stream-line effect to the pen, theresult being a more graceful appearance.

An ink wick support C holds a wick I 6 which latter traverses the inkduct I5 and maintains anl even flow of ink almost to the pen point. D isa spring clip of well known construction for attachment to the userspocket. The pump and pencil unit attached thereto likewise carry aspring clip, not shown.

From the foregoing it will now be apparent that when the nipple I4 isremoved, only the extreme end of the pen point is exposed, hence'thetendency of dust or foreign matter to clog the pen is greatly reduced.Again, in using a fountain pen, after the protective cover is removed,should the pen remain in this condition a few minutes without beingused, the ink being in contact with the outer air becomes dry and it isnecessary to shake the pen to force the ink downwardly onto the pointagain. In the present construction this is also greatly reduced.

While the foregoing describes a practical working embodiment of myinvention, I desire it understood that I do not limit my invention tothe precise construction shown and described, as my invention is capableof modifications and alteraa transparent tapered nipple secured over thesaid nipple w plug member, said tapered transparent having a piece ofmetal forming its lower end and provided with an aperture through whichonly the writing point oi' the pen extends, an ink duct extendingthrough the said plug member from the said nib to and communicating withthe transparent ink barrel, an ink wick extending from the nib throughthe ink duct in the plus member and reaching into the upper end of theink barrel. and a -support member being secured tothe inner end of thetonguelike vextension and extending into the ink barrel for the supportc! the said wick element.
